When coupled with our highest quality wrap wire you get consistent true tone that you can count on song after song. Martin Authentic Acoustic SP strings offer excellent tuning stability, corrosion resistance and great playability.

Review: Great Quality Strings - I’ve been using these same Martin strings on my Taylor GA4 and Mini GS for over a decade. I work on a lot of guitars. When I do setups from acoustic guitars I use these same strings unless my customer asks for something else.
Review: Just as described - Arrived just as described. Very pleased
